Going to try a 20 this year as the it will be easier to pack for this old bod. Anyway, I'm in California so I have to use non lead. Probably go with the Federal Heavyweight Turkey in #7. Usually use Kicks Gobbling Thunder in my 12's but understand they are not recommended for 20 heavyweight, so what do you guy's recommend? What choke do you feel is a good one for this load and what constriction do you use
